Question

Without plotting the points indicate the quadrant in which they will lie, if 

(i) ordinate is 5 and abscissa is – 3. 

(ii) abscissa is – 5 and ordinate is – 3. 

(iii) abscissa is – 5 and ordinate is 3.

Answer 1

Abscissa means x-axis (points on xx’ or x-axis) and ordinate means y-axis (points on yy’ or y-axis) 

(i) If ordinate is 5 and abscissa is – 3 

=> It represents the point (- 3, 5) 

=> Which is in II quadrant. 

(ii) If abscissa is -5 and ordinate is – 3 

=> It represents the point (-5, – 3) = III quadrant. 

(iii) If abscissa is – 5 and ordinate is 3 

=> It represents the point (- 5, 3) = II quadrant.
